Tiger spotter

New software developed with help from the Wildlife Conservation Society (WCS) will allow tiger researchers to rapidly identify individual animals by creating a three-dimensional model using photos taken by remote cameras. It may also help identify the origin of tigers from confiscated skins.

The software, developed by Conservation Research, creates a 3D model from scanned photos using algorithms similar to fingerprint-matching software used by criminologists.

Researchers calculate tiger populations by painstakingly reviewing hundreds of photos of animals caught by camera 'traps' and then matching their individual stripe patterns, which are unique to each animal.

Using a formula developed by tiger expert Ullas Karanth of WCS, researchers accurately estimate local populations by how many times individual tigers are 'recaptured' by the camera-trap technique.

It is expected that the software will allow researchers to rapidly identify animals, which in turn could speed up tiger conservation efforts.

Karanth, senior conservation scientist at the WCS, said: 'This new software will make it much easier for conservationists to identify individual tigers and estimate populations.
